Basic Heat Exchanger

For many types of furnaces, including oil and gas furnaces, the heat exchanger is the key component that makes the system work.

Closing Up the Air Conditioner for Winter

It sure doesn’t seem like fall is close but we are just a couple days away from September. As we get closer to the end of the air conditioning season we need to make sure we protect our air conditioners from the winter elements. Many units get damaged during winter months simply due to not being protected. Tree debris, ice and snow all can damage your unit during the fall and winter months.

Finding the Right Fit for Your AC Cover

Most manufacturers recommend protecting your unit with a proper fitting cover. Covers that are two big can allow debris into the unit and covers that are plastic or a poor fit will cause moisture to remain in the unit causing them to rust. A cover designed specifically for your unit gives you maximum protection at a minimum cost. So protect your air conditioner and contact your HVAC dealer to get a cover that fits and protects without causing damage.

Suspicious Coupons may be a Scam!

It seems like every time you check the mail there is a new coupon from some heating and cooling company offering their services at a discount rate. Right now the big service that is being pushed is air conditioner maintenance, and if you care about the condition of your air conditioner, odds are you have this service performed every year. The economy has everyone looking for ways to save, so those coupons are going to catch your attention. Illegitimate HVAC companies realize your need to save, and use it to their advantage. Don’t fall for their cheap tricks, and you will put your hard earned money to good use instead of wasting it on an air conditioner maintenance scam.

Low Pricing Red Flags

As you collect your air conditioner maintenance coupons, take a moment to notice the difference between the prices from one company to the next. You will find that some companies offer prices in the 70-90 dollar range, and other will offer the same service for 20-30 dollars. How is this possible? Are the high end companies just looking to make a bigger profit? No, they aren’t, and they are not the scam artists in this situation. Performing a cleaning for 70-90 dollars is the lowest a company would be able to go and still pull a small profit from the service. The companies that offer the extremely low pricing are the ones that should raise red flags in your mind. Continue reading
